photo, video and graphic design

Comparison: HDR and RAW

The photo on the left was created using 3 different exposure and on the right touched up by photo shop with RAW photo. By comparison, it look like photo taken using RAW look better than 3 different exposure HDR photo technique. HDR suppose to look better theoretically because the mix of three different exposure create a wider range of light and shadow in the photo to touch up in photo shop. Must be something wrong with the process or the exposure setting.
